It is clear from the evidence available that JFK was behind the foliage Z190-z200 and I think we can dispense with the notion the assassin would be firing through the oak tree. Obviously your only recourse is to question the validity of the evidence as it blows your notion of a shot this early out of the water. Interestingly it also refutes the memory of Phil Willis that he was startled by a shot this early.
At best you would have us believe the very instant JFK emerged from behind the last leaf of foliage the shot was taken. This makes no sense. The assassin may have tracked the limo through the foliage but the shot would have been taken once the limo was in the clear, say z223
The FBI re-enactment, even with its many errors, shows that JFK was visible by z200. A first shot at z223 is all perfectly reasonable and logical - except your reason and logic is not evidence and, more importantly, your conclusion does not fit large bodies of consistent evidence. I will explain:
1. As you have noted, the evidence is rather overwhelming that JFK reacted to the first shot. There are at least 20 witnesses who saw him react immediately and not a single witness said that he continued to smile and wave after the first "horrible ear-shattering noise"
2. The shot pattern recalled by the vast majority of witnesses (over 40 by my count) was the last two shots were closer together but not so close as to be impossible to have been fired by the MC, which requires around 2.3 seconds to fire successive aimed shots. There is strong evidence that at least one bullet was fired by Oswald's MC. (There is also strong evidence that all three shots came from the SN using the MC). In order for the first shot to have been at z223, the third shot could not have been as early as z313 in order to fit the shot pattern: 1.......2...3 and have close to 2.3 seconds between the last two shots. Therefore there must have been a third shot after z313. There is quite a body of evidence that z313 was the last shot so one would have to discard that evidence.
3. If the SBT occurred at z223 then Gov. Connally (and his wife) was hallucinating when he said that he heard the first shot, realized it was a rifle shot and turned to look at JFK saying "oh, no, no, no" (as Nellie recalled) before the second shot hit him with an impact that he felt (but did not hear) and which Nellie saw. So you have to throw out the Connally's evidence. You also have to throw out Greer's evidence which is that he turned around to see Gov. Connally falling back onto his wife immediately after the second shot. He is already lying down by z313.
The problem here is that everyone has looked at the zfilm and concluded that they can "see" the shot hitting both men at that time. They both react together if you assume that JFK is not already reacting behind the sign and just begins to react immediately as the bullet strikes him at z223 (another conjecture). JBC
said he reacted to the first shot. And JBC insisted that his reaction was well before he felt the second shot that hit him in the back. So we cannot judge by his reaction, even if it was "simultaneous" with JFK reacting, that he was hit in the back at that time if those reactions are to the first shot (which, as you agree, according to the evidence, there was only one shot to that point).
Btw do you have any reasonable explanation of why Connally's jacket suddenly billows a fraction of a second before both Kennedy and Connally simultaneously violently react?
As far as the jacket "bulge" is concerned, originally, this was a theory of a lapel flip until someone pointed out that the lapel was not struck. Then the armchair Rorschach experts opined that it was a jacket "bulge". To suggest that a bullet exiting the right jacket pocket is going to bulge the jacket needed experimental confirmation. Certainly a bullet alone is not going to do that, as experiments showed. That is because in order to impart momentum to the jacket the bullet has to lose momentum in passing through the cloth. It loses so little momentum in passing through that jacket cloth that the bullet would not move the entire jacket panel significantly. So then the story changed to - oh, the jacket bulged because the impact from the spray of blood and tissue exiting from the chest caused this. Again another conjecture without evidence or experimental support. The jacket bears no evidence of such blood and tissue:
Oh, yes. But Nellie had the jacket cleaned.... and the story goes on.
What we see in
those frames is a change in the amount of white shirt that is visible to Zapruder. There is no discernible "bulge" in the jacket. The decrease in white shirt is consistent with the jacket moving over it because JBC is moving. After all, we agree that JBC
is physically reacting. He is preparing to turn around as he does in subsequent frames. As he moves his right arm up from a resting position and he prepares to turn around to the rear, the jacket moves.
